The take U.S 6 North to Colorado 93, then Colorado Hwy 93 to Boulder (20 miles from Golden to Boulder) This trip should take about 2 to 2.5 hours. From Boulder to Denver, travel 30 miles (40 minutes) on U.S. Hwy 36. From Denver to Colorado Springs on I-25 is 70 miles, about 1.5 hours. So a one day drive-by round-trip would be 200 miles and five hours of in-traffic driving, leaving several hours for sightseeing.
